Abstract
Description
Technical Field
[0001] The present application relates to the field of oral cleaning, and more specifically, to an oral care device. Background Art
[0002] An oral care device is an electric device that uses a high-speed vibration movement motor to drive the brush head to rotate or vibrate to clean teeth. According to user needs, an antenna for sending and / or receiving external signals may be provided in the oral care device to send operating information to a control terminal or cloud, or to receive instructions sent by a terminal or cloud. However, the antenna currently installed in the oral care device needs to penetrate the internal structure or shell of the oral care device when sending and / or receiving signals, resulting in more signal loss and poor transmission efficiency. Utility Model Content
[0003] The embodiments of the present application provide an oral care device, which is at least used to solve the problem of poor antenna signal transmission efficiency in the oral care device.
[0004] The oral care device of the embodiment of the present application includes a handle shell, a circuit board disposed in the handle shell, a communication component disposed in the handle shell, and an electrical connector disposed in the handle shell. The handle shell is provided with a signal area. The communication component includes a communication module, and the communication module is disposed on the circuit board and electrically connected to the circuit board. The communication module is electrically connected to the signal area of the handle shell through the electrical connector, and the signal area of the handle shell and the communication module together form a signal transceiver, and the signal transceiver is used to send signals to the handle shell and / or receive signals outside the handle shell.
[0005] After the communication module is electrically connected to the signal area of the handle shell, the communication module and the signal area of the handle shell can jointly form a signal transceiver. At this time, the signal sent by the signal transceiver can be directly transmitted to the outside of the handle shell through the signal area of the handle shell, and the signal sent by the external device can also be directly received by the signal area of the handle shell. The signal does not need to pass through the handle shell during the transmission process, the signal loss is less, and the signal transmission efficiency is better.
[0006] In some embodiments, the electrical connector is an elastic member, one end of which is fixed to the circuit board and electrically connected to the communication module, and the other end of the electrical connector forms a contact electrical connection with the inner wall of the signal area of the handle shell.
[0007] When the electrical connector is installed on the circuit board and electrically connected to the communication module, the elastic electrical connector can be deformed between the circuit board and the communication module and abut against the communication module, so that the connection between the electrical connector and the communication module is more stable and less prone to circuit breaking or poor contact.
[0008] In some embodiments, the handle shell includes a handle tube and a bottom cover, the bottom cover is installed at the bottom end of the handle tube, the signal area is arranged on the bottom cover, and the electrical connector abuts against the signal area on the bottom cover.
[0009] When the signal area is provided on the bottom cover, the signal can be directly transmitted to the outside through the signal area of the bottom cover, or the signal sent by the external device can be received through the signal area of the bottom cover. At this time, the signal receiving and transmitting area corresponding to the signal area can be completely located within the range where the bottom cover is located, so as to reduce the influence of the metal handle tube on the signal receiving and transmitting function of the antenna, and ensure the transmission quality and signal strength of the signal.
[0010] In some embodiments, a protruding and extending abutment sheet is provided on the bottom cover, the signal area includes the abutment sheet, and the electrical connector abuts against the abutment sheet.
[0011] The abutment sheet is a conductive structure extending from the bottom cover. Compared with the signal area on the bottom cover, the abutment portion can be arranged closer to the electrical connector, so that the electrical connector does not have to extend a long distance to be electrically connected to the bottom cover through the abutment sheet. The electrical contact quality between the two is better and the signal transmission is more stable.
[0012] In some embodiments, the bottom cover includes a metal blocking portion and a non-metallic connecting portion. The blocking portion is used to block the opening at the bottom end of the handle tube, the signal area is provided on the blocking portion, and the electrical connector abuts against the signal area on the blocking portion. The connecting portion is connected to the blocking portion and is provided in the handle tube, and the connecting portion avoids the signal area on the blocking portion.
[0013] Since the non-metallic joint has poor electrical conductivity, the electrical connector needs to pass through or bypass the joint when electrically connected to the signal area on the blocking part to improve the quality of signal transmission. The joint can be used to combine with the handle tube and prevent the handle tube from falling off from the bottom cover, thereby improving the stability of the electrical connection between the electrical connector and the signal area on the blocking part.
[0014] In some embodiments, the oral care device further comprises an inner liner, wherein the inner liner is disposed in the handle shell and connected to the handle shell, and the coupling portion is used to be connected to the inner liner.
[0015] Since the handle shell is made of metal, the internal structure of the oral care device is difficult to fix on the metal handle shell, and the cost of making a fixed structure in the metal handle shell is high. The non-metallic liner can be used to connect the internal structure of the oral care device and the bottom cover, which can reduce the manufacturing cost of the oral care device on the one hand, and prevent the internal structure of the oral care device from shaking in the handle shell on the other hand, thereby protecting the internal structure of the oral care device. At the same time, the non-metallic liner can also be firmly connected to the non-metallic joint, so that the bottom cover can be tightly combined with the metal handle shell.
[0016] In some embodiments, the oral care device further comprises a core assembly disposed in the handle shell, and the circuit board has a protrusion. In the direction of the central axis of the handle shell, the protrusion protrudes toward the bottom cover relative to the core assembly, and the communication module and the electrical connector are both disposed on the protrusion.
[0017] Compared with a solution in which the circuit board is not provided with a protrusion, the communication module and the electrical connector on the protrusion can be staggered with the movement assembly, so that the communication module and the electrical connector can partially bypass the movement assembly and be closer to the signal area of the bottom cover and / or the signal area of the handle tube wall. On the one hand, it can prevent the movement assembly from blocking the signal propagation path of the signal transceiver receiving and / or sending signals. On the other hand, the protrusion extending toward the bottom cover is also used to make the communication module and the electrical connector provided on the protrusion closer to the signal area, thereby improving the signal transmission efficiency and making the internal structure of the oral care device more tightly arranged.
[0018] In some embodiments, the handle shell includes a handle barrel and a bottom cover, and the bottom cover is installed at the bottom end of the handle barrel. The signal area is provided on the handle barrel, and the electrical connector abuts against the signal area on the handle barrel.
[0019] When the signal area is arranged on the handle tube, the signal area can be located at any position of the handle tube. At this time, the electrical connector can also be a wire arranged in the handle tube and capable of connecting the communication module on the circuit board and the signal area. Moreover, the signal area arranged at any position on the handle tube can also send signals in different directions or receive external signals from different directions. The signal area has a wider range of receiving signals or sending signals outward.
[0020] In some embodiments, the oral care device further comprises an inner liner and a core assembly. The inner liner is disposed in the handle shell and connected to the handle shell. The core assembly is disposed in the inner liner and connected to the inner liner, and the electrical connector passes through and / or bypasses the inner liner to abut against the signal area.
[0021] When the inner peripheral wall of the liner and the outer peripheral wall of the core assembly are combined with each other, the core assembly can be installed in the liner, and the core assembly will not shake or rotate violently in the liner, thereby improving the stability of the connection between the structures in the oral care device. Since the shells of the liner and the core assembly are both non-conductive non-metallic materials, the electrical connector needs to pass through and / or bypass the shells of the liner and the core assembly so that the communication module can always be electrically connected to the signal area.
[0022] In some embodiments, the electrical connector includes at least one of a wire and a flexible circuit board. One end of the electrical connector is electrically connected to the communication module, and the other end of the electrical connector is electrically connected to the inner wall of the signal area of the handle shell by copper welding or bonding.
[0023] When the other end of the electrical connector is electrically connected to the inner wall of the signal area by copper welding or bonding, the electrical connector and the signal area are always in a stable electrical connection state. On the one hand, the electrical connector is not easy to fall off from the inner wall of the signal area. On the other hand, the circuit connection between the two is more stable and there will be no intermittent circuit breakage.
[0024] In some embodiments, the signal region is formed of antenna material.
[0025] Compared with other conductive materials, antenna materials can convert high-frequency current or waveguides into radio waves or free electromagnetic waves and radiate them to the surrounding space to generate a larger radiation field. At the same time, antenna materials can also receive radio waves and convert them into high-frequency current or waveguides. After using antenna materials, the distance of signal transmission can be greatly increased, and the stability of signal transmission is better.
[0026] In some embodiments, the handle shell is further provided with a non-signal area. The signal area is made of antenna material, and the material of the non-signal area is different from that of the signal area.
[0027] The non-signal area can be made of a material electrically insulated from the signal area. When the material of the non-signal area is different from that of the signal area, the non-signal area and the signal area will not affect each other, thus avoiding the occurrence of turbulent waves that affect the quality of signal transmission.
[0028] In some embodiments, the handle shell is made of all metal, and the metal material of the signal area is different from the metal material of the non-signal area.
[0029] When both the signal area and the non-signal area are metal, the non-signal area can be made of ordinary conductive material that cannot convert high-frequency current and radio waves. Therefore, the non-signal area and the signal area will not affect each other, and the quality of signal transmission can be prevented from being affected by turbulence.
[0030] In some embodiments, the distance between the signal area and the top end of the handle shell does not exceed 1 / 4 of the total length of the handle shell. Or, the distance between the signal area and the bottom end of the handle shell does not exceed 1 / 4 of the total length of the handle shell.
[0031] Setting the signal area at a distance less than 1 / 4 of the total length of the handle shell from the top end or the bottom end of the handle shell can enable the signal transceiver to be located on the side of the handle shell closer to the top end or the side closer to the bottom end, thereby avoiding the signal transceiver path of the signal area being blocked when the user holds the oral care device.

[0049] See also Figure 1 and Figure 2 , and combined with Figure 4 The oral care device 100 of the present application includes a handle shell 10, a circuit board 20 disposed in the handle shell 10, a communication component 30 disposed in the handle shell 10, and an electrical connector 40 disposed in the handle shell 10. The handle shell 10 is provided with a signal area 101. The communication component 30 includes a communication module 31, and the communication module 31 is disposed on the circuit board 20 and electrically connected to the circuit board 20. The communication module 31 is electrically connected to the signal area 101 of the handle shell 10 through the electrical connector 40, and the signal area 101 of the handle shell 10 and the communication module 31 together form a signal transceiver, which is used to send signals to the handle shell 10 and / or receive signals outside the handle shell 10.
[0050] In the oral care device 100 of the present application, after the communication module 31 is electrically connected to the signal area 101 of the handle shell 10, the communication module 31 and the signal area 101 of the handle shell 10 can jointly form a signal transceiver. At this time, the signal sent by the signal transceiver can be directly transmitted to the outside of the handle shell 10 through the signal area 101 of the handle shell 10, and the signal sent by the external device can also be directly received by the signal area 101 of the handle shell 10. The signal does not need to pass through the handle shell 10 during the transmission process, the signal loss is less, and the signal transmission efficiency is better.
[0051] The oral care device 100 is further described below with reference to the accompanying drawings.
[0052] See also Figure 1 and Figure 2In some embodiments, the handle shell 10 is roughly a shell structure that can accommodate part of the structure of the oral care device 100. Part of the structure of the oral care device 100 can be set in the handle shell 10. The material of the handle shell 10 includes but is not limited to metal or alloy. During the propagation of the signal, the handle shell 10 will seriously affect the transceiver performance of the signal area 101. At the same time, the handle shell 10 will also absorb and shield the signal emitted by the signal area 101 or the signal transmitted from the external device to the signal area 101, resulting in a large loss of the signal during the transmission process, making it difficult to accurately transmit information or instructions. The communication module 31 disposed in the handle shell 10 can be electrically connected to the signal area 101 disposed on the handle shell 10, so that the current emitted by the communication module 31 can be converted into a signal directly emitted outward through the signal area 101, or the external signal received by the signal area 101 can be converted into a current that can be recognized by the communication module 31, and the signal loss caused when the signal passes through the handle shell 10 is reduced.
[0053] Specifically, in some embodiments, the handle shell 10 includes a top end and a bottom end that are disposed opposite to each other, and the handle shell 10 has a central axis A. The central axis A of the handle shell 10 is an axis that divides the handle shell 10 into two relatively symmetrical parts. When the handle shell 10 is an axisymmetric three-dimensional structure, the central axis A of the handle shell 10 passes through the center of the top end of the handle shell 10 and the center of the bottom end of the handle shell 10, that is, the direction X of the central axis A of the handle shell 10 can be either a straight line extending direction from the center of the top end of the handle shell 10 to the center of the bottom end of the handle shell 10, or a straight line extending direction from the center of the bottom end of the handle shell 10 to the center of the top end of the handle shell 10, which is not limited here. The direction Y perpendicular to the central axis A of the handle shell 10 can be any straight line extending direction of the opposite sides of the handle shell 10, which is not limited here. The outer contour shape of the cross section of the handle shell 10 includes but is not limited to a perfect circle, an ellipse, a triangle, a quadrilateral or a pentagon, etc. In some embodiments, along the direction X of the central axis A of the handle shell 10, from the bottom end of the handle shell 10 to the top end of the handle shell 10, the outer contour size of the cross section of the handle shell 10 gradually changes, for example: the outer contour size of the cross section of the handle shell 10 first remains unchanged and then gradually decreases, first increases and then decreases, or changes multiple times. In other embodiments, along the direction X of the central axis A of the handle shell 10, from the bottom end of the handle shell 10 to the top end of the handle shell 10, the outer contour size of the cross section of the handle shell 10 always remains unchanged.
[0054] More specifically, in some embodiments, the handle shell 10 includes a handle barrel 11 and a bottom cover 13. The handle barrel 11 is a generally cylindrical structure. The handle barrel 11 includes a top end 111 (i.e., the top end of the handle shell 10) and a bottom end 113 (i.e., the bottom end of the handle shell 10) facing each other. The bottom end of the handle barrel 11 is open, and a part of the structure of the oral care device 100 can extend from the opening into the handle barrel 11 and be installed in the handle barrel 11. The bottom cover 13 is installed at the bottom end 113 of the handle barrel 11 and can be arranged at the opening to block the opening to prevent external dust, water vapor, liquid or foam from entering the handle barrel 11 and causing damage to the part of the structure of the oral care device 100 in the handle barrel 11. In some embodiments, at least part of the structure of the handle barrel 11 and the bottom cover 13 is made of metal, and the materials of the handle barrel 11 and the bottom cover 13 include but are not limited to aluminum, iron and alloys thereof. In other embodiments, at least part of the structure of the handle tube 11 and the bottom cover 13 is made of non-metallic material, and the materials of the handle tube 11 and the bottom cover 13 include but are not limited to plastic, silicone or rubber.
[0055] Furthermore, please combine Figure 3 In some embodiments, the signal area 101 is an area that can convert the high-frequency current or waveguide emitted by the communication module 31 into radio waves or free electromagnetic waves and radiate them to the surrounding space to generate a larger radiation field. In addition, the signal area 101 can also receive radio waves or free electromagnetic waves sent by external terminals or the cloud and convert them into currents or waveguides that can be recognized by the communication module 31. In some embodiments, the signal area 101 uses antenna materials. The types of antenna materials include but are not limited to metals, ceramics, or glass fibers. Compared with other conductive materials, the distance of signal transmission emitted by the signal area 101 can be greatly increased after using antenna materials, and the stability of signal transmission is better. In addition, the signal area 101 can receive a wider range of signals, and the information obtained from the received signals is more complete.
[0056] Specifically, please combine Figure 4 and Figure 6 In some embodiments, Figure 2 As shown, the signal area 101 is provided on the bottom cover 13, one end of the electrical connector 40 is electrically connected to the communication module 31 to transmit current or waveguide, and the other end of the electrical connector 40 abuts against the signal area 101 on the bottom cover 13 to transmit current or waveguide to the signal area 101 on the bottom cover 13. In the case where the signal area 101 is provided on the bottom cover 13, the signal can be directly transmitted outward through the signal area 101 of the bottom cover 13, or the signal sent by the external device can be received through the signal area 101 of the bottom cover 13. At this time, the signal transceiver area corresponding to the signal area 101 can all be located within the range where the bottom cover 13 is located, so as to reduce the influence of the structure of the oral care device 100 on the signal transceiver function of the antenna, and ensure the transmission quality and signal strength of the signal. In other embodiments, such as Figure 1 As shown, the signal area 101 is provided on the handle barrel 11, one end of the electrical connector 40 is electrically connected to the communication module 31 to transmit current or waveguide, and the other end of the electrical connector 40 abuts against the signal area 101 on the handle barrel 11 to transmit current or waveguide to the signal area 101 on the handle barrel 11. In the case where the signal area 101 is provided on the handle barrel 11, the signal area 101 can be located at any position of the handle barrel 11. At this time, the electrical connector 40 can also be a wire provided in the handle barrel 11 and capable of connecting the communication module 31 on the circuit board 20 and the signal area 101. Moreover, the signal area 101 provided at any position on the handle barrel 11 can also send signals in different directions or receive external signals from different directions. The range of the signal area 101 receiving signals or sending signals outward is wider. In some other embodiments, Figure 7 and Figure 8 As shown, the signal area 101 includes at least two, and the at least two signal areas 101 can be respectively arranged on the bottom cover 13 and the handle tube 11, so that the signal receiving and transmitting range of the oral care device 100 is wider.
[0057] Furthermore, please combine Figure 6 In some embodiments, the handle shell 10 is further provided with a non-signal area 103, and the non-signal area 103 is a partial structure that cannot receive signals or send signals outward. The non-signal area 103 can be connected to the non-signal area 103, or it can be isolated from the signal area 101. The non-signal area 103 can be provided on the handle tube 11, or it can be provided on the bottom cover 13. In some embodiments, the non-signal area 103 can be a material that is electrically insulated from the signal area 101. In other embodiments, the non-signal area 103 can be electrically connected to the signal area 101 to achieve different functions. For example: the non-signal area 103 is an electric trigger button. When the non-signal area 103 detects current, the electric trigger button can control the opening or closing of the oral care device 100. Preferably, please combine Figure 8 The material of the non-signal area 103 is generally different from that of the signal area 101. When the material of the non-signal area 103 is different from that of the signal area 101, the non-signal area 103 and the signal area 101 will not affect each other, thus avoiding the occurrence of turbulence that affects the quality of signal transmission.
[0058] Specifically, in some embodiments, when the handle shell 10 is made of all-metal material, the signal area 101 and the non-signal area 103 are both made of metal materials, and the metal material of the signal area 101 is different from the metal material of the non-signal area 103. When both the signal area 101 and the non-signal area 103 are made of metal, the non-signal area 103 can be a common conductor material that cannot convert high-frequency current and radio waves into each other. Therefore, the non-signal area 103 and the signal area 101 will not affect each other, and the quality of signal transmission can be avoided after the occurrence of turbulence.
[0059] Furthermore, please combine Figure 3 In some embodiments, along the direction X of the central axis A of the handle shell 10, the distance H1 between the signal area 101 and the top 111 of the handle tube 11 does not exceed 1 / 4 of the total length H0 of the handle shell 10. When the signal area 101 is set at a position where the distance H1 between the signal area 101 and the top 111 of the handle tube 11 is less than 1 / 4 of the total length H0 of the handle shell 10, the signal area 101 can be located on the side of the handle shell 10 closer to the top 111 of the handle tube 11. At this time, the signal area 101 is set on the peripheral wall of the handle tube 11, and the signal area 101 is also set on the side closer to the top 111 of the handle tube 11 relative to the handle tube 11. In the case where the signal area 101 is located on the side of the handle shell 10 closer to the top 111 of the handle tube 11, the signal area 101 and the position where the user holds the oral care device 100 can be staggered and the signal receiving and transmitting path of the signal area 101 can be avoided when the user holds the oral care device 100. In other embodiments, along the direction X of the central axis A of the handle shell 10, the distance H2 between the signal area 101 and the bottom end 113 of the handle tube 11 does not exceed 1 / 4 of the total length H0 of the handle shell 10. When the signal area 101 is set at a position where the distance H2 between the signal area 101 and the bottom end 113 of the handle tube 11 is less than 1 / 4 of the total length H0 of the handle shell 10, the signal area 101 can be located on the side of the handle shell 10 closer to the bottom end 113 of the handle tube 11. In this case, the signal area 101 is set on the bottom cover 13, and the signal area 101 is set on the side closer to the bottom end 113 of the handle tube 11 relative to the handle tube 11. In the case where the signal area 101 is located on the side of the handle shell 10 closer to the bottom end 113 of the handle tube 11, the signal area 101 and the position where the user holds the oral care device 100 can be staggered and the signal transmission and reception path of the signal area 101 can be avoided when the user holds the oral care device 100.
[0060] Furthermore, in some embodiments, the bottom cover 13 includes a metal blocking portion 131 and a non-metallic coupling portion 133. The blocking portion 131 extends from a side of the coupling portion 133 close to the bottom end 113 of the handle tube 11 into the handle tube 11, and the coupling portion 133 is connected to the blocking portion 131 and is disposed in the handle tube 11. The blocking portion 131 is generally a plate-shaped structure, and the blocking portion 131 can block the opening of the bottom end 113 of the handle tube 11 to isolate the internal structure of the oral care device 100 from the outside and prevent water vapor or dust from entering the oral care device 100. The coupling portion 133 can be used to combine with the handle tube 11 and prevent the handle tube 11 from falling off from the bottom cover 13, thereby improving the stability of the electrical connection between the electrical connector 40 and the signal area 101 on the blocking portion 131. In some embodiments, the coupling portion 133 is roughly a hook structure or a plate structure that extends into the handle tube 11 and can be connected to the handle tube 11, so that the bottom cover 13 can be installed on the handle tube 11. In other embodiments, the coupling portion 133 is roughly a cylindrical structure with a cavity inside. The signal area 101 is provided on the blocking portion 131, the electrical connector 40 abuts against the signal area 101 on the blocking portion 131, and the coupling portion 133 can avoid the signal area 101 on the blocking portion 131. Since the non-metallic coupling portion 133 has poor electrical conductivity, the electrical connector 40 needs to pass through or bypass the coupling portion 133 when electrically connected to the signal area 101 on the blocking portion 131 to improve the quality of signal transmission.
[0061] Specifically, please combine Figure 4 In some embodiments, a protruding and extending abutting piece 1301 is provided on the bottom cover 13. The abutting piece 1301 is a conductive structure extending from the bottom cover 13. In some embodiments, the abutting piece 1301 passes through or bypasses the joint 133 to be directly connected to the blocking portion 131. In this case, the signal area 101 includes the abutting piece 1301 and at least part of the structure of the blocking portion 131. In other embodiments, the abutting piece 1301 is connected to the joint 133, and the signal area 101 only includes the abutting piece 1301. One end of the electrical connector 40 is electrically connected to the communication module 31, and the other end of the electrical connector 40 abuts against the abutting piece 1301. Compared with the signal area 101 on the bottom cover 13, the abutting portion can be arranged closer to the electrical connector 40, so that the electrical connector 40 does not need to extend a long distance to be electrically connected to the bottom cover 13 through the abutting piece 1301, the electrical contact quality between the two is better, and the signal transmission is more stable.
[0062] See also Figure 2 and Figure 4 , and combined with Figure 1In some embodiments, the communication component 30 is generally a structure that can send out signals according to instructions or receive and read signals sent by an external device to the oral care device 100 to obtain instructions. The types of communication components 30 include but are not limited to WIFI modules, Bluetooth modules or Zigbee modules. The circuit board 20 is a structure for electrically connecting to the communication component 30 to supply power to the communication component 30. In some embodiments, the communication module 31 of the communication component 30 is disposed on the circuit board 20 and is directly electrically connected to the circuit board 20. In other embodiments, such as Fig.10 As shown, the communication module 31 is disposed on the signal area 101 of the handle shell 10 (located on the handle tube 11 or the bottom cover 13) and is indirectly electrically connected to the circuit board 20. The communication module 31 can transmit current or waveguide to the signal area 101 or receive current or waveguide transmitted by the signal area 101 through the electrical connector 40, so as to realize the function of the oral care device 100 sending signals to the outside or receiving signals sent by an external terminal or the cloud.
[0063] See also Figure 2 and Figure 4 , and combined with Figure 1 In some embodiments, the electrical connector 40 is a structure capable of electrically connecting the communication module 31 and the signal area 101 or a structure electrically connecting the circuit board 20, the communication module 31 and the signal area 101. The electrical connector 40 can be an independent conductive member, such as a wire (such as Figure 7 ), or a hard circuit board 20 or a flexible circuit board 20 (such as Figure 8 The electrical connector 40 includes a first end and a second end facing each other, the first end 41 of the electrical connector 40 is electrically connected to the communication module 31 , and the second end 43 of the electrical connector 40 is electrically connected to the signal area 101 of the handle housing 10 .
[0064] In some embodiments, please combine Figure 5, the second end 43 of the electrical connector 40 is electrically connected to the inner wall of the signal area 101 of the handle shell 10 by copper leakage welding or bonding. At this time, the second end 43 of the electrical connector 40 is non-detachably fixedly connected to the inner wall of the signal area 101 of the handle shell 10, and the electrical connector 40 and the signal area 101 are always in a stable electrical connection state. On the one hand, the electrical connector 40 is not easy to fall off from the inner wall of the signal area 101, and on the other hand, the circuit connection between the two is more stable, and there will be no intermittent circuit breakage. In other embodiments, the electrical connector 40 is an elastic member, such as a spring or a spring pin. The first end 41 of the electrical connector 40 is fixed to the circuit board 20 and can be electrically connected to the communication module 31, and the second end 43 of the electrical connector 40 forms a contact-type electrical connection with the inner wall of the signal area 101 of the handle shell 10. At this time, the second end 43 of the electrical connector 40 and the inner wall of the signal area 101 of the handle shell 10 are detachably and removably connected. The elastic electrical connector 40 can be deformed or micro-deformed between the circuit board 20 and the communication module 31 and abut against the communication module 31, so that the connection between the electrical connector 40 and the communication module 31 is more stable and less prone to circuit breaks or poor contact.
[0065] See also Figure 2 and Figure 3 In some embodiments, the oral care device 100 further includes an inner liner 50. The inner liner 50 is generally a cylindrical structure disposed in and connected to the handle barrel 11. The material of the inner liner 50 includes, but is not limited to, non-metallic materials such as plastic, silicone or rubber. Compared with the metal handle barrel 11, the inner liner 50 can be more firmly connected to the structure in the oral care device 100, reducing the shaking and collision of the internal structure in the oral care device 100. In some embodiments, the inner liner 50 can be integrally formed in the handle barrel 11. In other embodiments, the inner liner 50 is a structure installed in the handle barrel 11 after being separately formed. The outer contour size of the cross section of the inner liner 50 is less than or equal to the inner contour size of the cross section of the handle barrel 11, so that the inner liner 50 can be installed in the handle barrel 11. Since the handle barrel 11 is made of metal, the internal structure of the oral care device 100 is difficult to be fixed in the metal handle barrel 11, and the cost of making a fixed structure in the metal handle barrel 11 is high. The non-metallic lining 50 can be used to connect the internal structure of the oral care device 100 and the joint 133 of the bottom cover 13, which can reduce the manufacturing cost of the oral care device 100 on the one hand, and prevent the internal structure of the oral care device 100 from shaking in the handle tube 11 on the other hand, thereby protecting the internal structure of the oral care device 100.
[0066] Furthermore, please combine Figure 4In some embodiments, the joint 133 of the bottom cover 13 is connected to the liner 50, and the non-metallic liner 50 can also be firmly connected to the non-metallic joint 133, so that the bottom cover 13 can be tightly combined with the metal handle tube 11. The materials of the joint 133 and the liner 50 can be the same or different. The joint 133 and the liner 50 can be connected by a non-detachable method such as hot melt connection or adhesive connection, or by a detachable method such as threaded connection, snap connection or bolt connection, which is not limited here. In other embodiments, the bottom cover 13 is connected to the handle tube 11. In one example, the joint 133 of the bottom cover 13 can extend into the handle tube 11 and be connected to the handle tube 11 and the liner 50 at the same time. In another example, the joint 133 of the bottom cover 13 is only connected to the handle tube 11 and is separated from the liner 50.
[0067] See also Figure 1 and Figure 2 , and combined with Figure 4 In some embodiments, the oral care device 100 further includes a core assembly 60, which is a component installed in the handle shell 10 and capable of supporting and installing the circuit board 20 and other structures of the oral care device 100. The core assembly 60 is disposed in the handle tube 11. In some embodiments, the core assembly 60 is detachably mounted on the inner wall of the handle shell 10, and the mounting method includes but is not limited to threaded connection, snap connection or bolt connection. In other embodiments, the core assembly 60 is non-detachably fixed to the inner wall of the handle shell 10, and the fixing method includes but is not limited to hot melt connection, gluing connection or welding. In the case where only a part of the structure of the communication module 31 is electrically connected to the circuit board 20, a part of the structure of the communication module 31 can be fixed to the core assembly 60. The core assembly 60 can be used to install the communication module 31.
[0068] Furthermore, please combine Fig. 9 In some embodiments, the core assembly 60 is disposed in the liner 50 and connected to the liner 50, and the electrical connector 40 passes through and / or bypasses the liner 50 to abut against the signal area 101. The signal area 101 can be disposed on the bottom cover 13 or on the handle tube 11, and there is no limitation here. When the inner peripheral wall of the liner 50 and the outer peripheral wall of the core assembly 60 are combined with each other, the core assembly 60 can be installed in the liner 50, and the core assembly 60 will not shake or rotate violently in the liner 50, thereby improving the stability of the connection between the structures in the oral care device 100. Since the outer shells of the liner 50 and the core assembly 60 are both non-conductive non-metallic materials, the electrical connector 40 needs to pass through and / or bypass the outer shells of the liner 50 and the core assembly 60 so that the communication module 31 can always be electrically connected to the signal area 101.
[0069] Specifically, in some embodiments, the circuit board 20 further includes a protrusion 21, which is a partial structure formed by the circuit board 20 extending in the direction X of the central axis A of the handle housing 10 toward the bottom cover 13. The protrusion 21 protrudes toward the bottom cover 13 relative to the core assembly 60, that is, the protrusion 21 and the core assembly 60 are staggered and do not overlap each other along the direction Y perpendicular to the central axis A of the handle housing 10. The communication module 31 and the electrical connector 40 are both disposed on the protrusion 21. Compared with the solution in which the circuit board 20 is not provided with the protrusion 21, the communication module 31 and the electrical connector 40 on the protrusion 21 can be staggered with the movement assembly 60, so that the communication module 31 and the electrical connector 40 can partially bypass the movement assembly 60 and be closer to the signal area 101 of the bottom cover 13 and / or the signal area 101 of the peripheral wall of the handle tube 11. On the one hand, it can prevent the movement assembly 60 from blocking the signal propagation path of the signal transceiver receiving and / or sending signals. On the other hand, the protrusion 21 extending toward the bottom cover 13 is also used to make the communication module 31 and the electrical connector 40 provided on the protrusion 21 closer to the signal area 101, thereby improving the signal transmission efficiency and making the internal structure of the oral care device 100 more tightly arranged.
[0070] In summary, in the oral care device 100 of the present application, after the communication module 31 is electrically connected to the signal area 101 of the handle shell 10, the communication module 31 and the signal area 101 of the handle shell 10 can jointly form a signal transceiver. At this time, the signal sent by the signal transceiver can be directly transmitted to the outside of the handle shell 10 through the signal area 101 of the handle shell 10, and the signal sent by the external device can also be directly received by the signal area 101 of the handle shell 10. The signal does not need to pass through the handle shell 10 during the transmission process, the signal loss is less, and the signal transmission efficiency is better.
